Urban infrastructure projects:<\/b> We\u2019re used to working in demanding urban infrastructure environments, such as city centers, groundwater areas, and hospital sites. <\/span>Kaupunki-infrakohteissa meill\u00e4 on pitk\u00e4 kokemus tarkkuutta vaativista projekteista, joissa t\u00e4rin\u00e4n, p\u00f6lyn ja paineaaltojen hallinta on kriittist\u00e4.<\/span>
\n<\/span><\/p>\n

Mining construction:<\/b> We carry out, for example, full-scope mining contracts, production blasting, and mine development drifting.<\/span><\/p>\n

Excavation services:\u00a0<\/span><\/h2>\n

We provide all excavation and drilling work related to underground rock construction, excluding diamond drilling. Typical excavation projects include:<\/span><\/p>\n

    \n
  • Tunnel profiles of all sizes in infrastructure projects, from tight technical spaces to large cavern and hall profiles<\/span><\/span><\/li>\n
  • Widening and raising excavations in rehabilitation projects<\/span>
    \n<\/span><\/li>\n
  • Production blasting and mine development drifting in mines<\/span>
    \n<\/span><\/li>\n
  • Shafts<\/span><\/li>\n<\/ul>\n

    Methods and techniques<\/span><\/h2>\n

    The method is always selected to suit the site. We use both blasting and non blasting approaches, including:<\/span><\/p>\n

      \n
    • Longhole drilling and the Alimak method<\/b>
      \n<\/span><\/li>\n
    • Electronic detonators<\/b> in vibration sensitive areas<\/span>
      \n<\/span><\/li>\n
    • Louhinta kiilaamalla<\/b>
      \n<\/span><\/li>\n
    • Wire sawing and pre drilling <\/b>esimerkiksi puhkaisukohdissa<\/li>\n<\/ul>\n

      Safety and environmental control<\/span><\/h2>\n

      Especially in urban infrastructure and rehabilitation projects, taking the surrounding environment into account is essential in excavation work. We pay particular attention to:<\/span><\/p>\n

        \n
      • T\u00e4rin\u00e4herkkyyteen ja t\u00e4rin\u00e4mittauksiin (rakennukset, t\u00e4rin\u00e4herk\u00e4t laitteet)<\/span><\/li>\n
      • Protective measures required for excavation, such as blast walls, matting, dust tight sealing, and air pressure control<\/span><\/li>\n
      • Dust management and minimizing the site\u2019s environmental impact<\/span><\/li>\n<\/ul>\n

        Take excavation requirements into account early<\/span><\/h2>\n

        Tunneliurakoitsijan asiantuntemusta kannattaa hy\u00f6dynt\u00e4\u00e4 jo projektin suunnitteluvaiheessa. Erityisesti vaativissa saneerauskohteissa ota meihin yhteytt\u00e4 ajoissa – annamme mielell\u00e4mme n\u00e4kemyksemme kohteen toteuttamisesta ja autamme ratkomaan kohteen toteutettavuuteen liittyvi\u00e4 haasteita.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
